WebApr 5, 2024 · The calorific value defines the energetic content of the materials; it is the amount of heat a substance produces after complete combustion. You can express it as the gross calorific value (GCV) or high heating value. Also, the calorific value of a substance (generally, solid biofuel or food) is the specific energy of combustion for a unit mass. WebMeasurement of Food Calories The potential energy value of foods and the energy exchanges of the body are expressed in terms of the calorie, which is a heat unit.
